2013 StumpJumper HT Expert Carbon 29er

Just ordered one from my bike shop, anyone here have one and what's your take, do you like it (I've never ridden one before or seen one). What's the weight for your bike with or without mods. Also inread a common issue with this bike is the seat post where it connects top tube cracking easily and Specialized not honoring their warranty.
-Thanks

Also going through the specs, are they good for the price? It had like x7 and slx stuff on it which seems kind of low end for the price, also for only $500 more the marathon include carbon wheels and what seems to be much better componentry.

I Love It!

I've been riding mine for about three months now and I'm in love with it. Rode it stock for about a month and didn't feel the need to upgrade anything until the devil inside of me said "you know you want to." Now it sits just under 21lbs with the upgrades listed below. As for the "seat post where it connects top tube" being weak, I've had no issue with it yet and I weigh 260lbs at the moment. Hope you enjoy every ride on your new bike. I Do!
